MOBO: ASRock 970 extreme 4
RAM: Patriot G2 8GB dual channel @ 1600 MHz
BOOT HDD: WD Scorpio blue 320gb @ 7200RPM
DATA HDD WD Black 640gb @ 7200RPM
VGA CARD: (upgrading to) EVGA GTX 770 SC W/ ACX cooling 2gb
FANS: 3 Cooler Master MegaFlow 230mm blue LED, 1 Cooler Master 140mm blue LED
PSU: Rosewill HIVE 650w
OS: Windows 7 Professional 64bit
GPU: (current GPU) Gigabyte r9 270x Windforce 2x 2gb (this is why im upgrading)-http://www.tomshardware.com/answers/id-1977298/minecraf...

Your PSU can support the GTX 770. It offers 46A and the minimum recommended is 42A.

I'm calling BS on that other thread, my 7850 runs it just fine, and i have never encountered minecraft issues due to the GPU before. The most common cause of minecraft lag i have encountered is java needing an update, make sure you have the latest java and then see if it works any better before you blow that much money just to fix one game.

Also, yes a Hive 650W will do a 770 fine.

I have tried everything. updating java, updating gpu drivers to 13.12, i even tried using my friends r7 250 and got 150FPS

I see no reason to upgrade from a R9 270X to a 770. you had to have JUST bought the 270X. why change it?

and you say ADDING. you cannot add an nividia GPU to an AMD GPU. a rosewill hive 650W is of course overkill for a single 770.

as said that openGL crap in your other thread is nonsense. if its jumping clock rates like that its confusing its 2D and 3D clocks because minecraft is so low end. use Asus GPU tweak or another utility to lock the 3D clocks

and DON'T bump posts. read the forum rules man

MSI afterburner should also have a feature to lock the 3D clocks... course the info on your problem was not in this post. so....

Where is the setting for that?

I am sure there is one for MSI afterburner (not sure where) but I prefer ASUS GPU tweak. (has GPU monitoring and GPUz).

It should work on yours. if you have it up it should say:

ASUS GPU tweak( as the title)
second line
"3D" then your GPU series.

if you click on 3D it lets you select 2D and set the 2D clocks. now immediately to the left of "3D" is a 2 with a strike though. it looks like a weird swiggly line. if you click it it will say "do you want to disable 2D clocks"

hit ok and you are locked to the 3D clocks till you turn it off, even if the OS/Program gets confused

There is no button there. Just text that says 3D

the text that says 3D on mine is a button. even if you had to manually set 2D clocks that should fix it. do you have what version you are on or a screenshot? locking 3d clocks is a pretty normal feature.

obviously it just working would be better but this should be a simple fix

i manually set the 2d clock speed to match the 3d clock speeds. there was no performance increase.
